Panaji, Sep 8 (IANS): The mobbing of Delhi Chief Minister Arvind Kejriwal at the New Delhi railway station was "pre-planned" by the BJP and police did nothing to prevent it, AAP leader Manish Sisodia said on Thursday.

"The manner in which the attack occurred in the morning, Arvindji was mobbed, BJP women workers were present, TV crew were invited and cameras were present," the Deputy Chief Minister of Delhi said.

"The police were present but they didn't stop anything. They did not even stop. Therefore, it appears pre-planned," Sisodia told reporters on the sidelines of a conference in a city resort.

Kejriwal was mobbed by women BJP members who demanded an answer from the Delhi Chief Minister over allegations that women had been exploited in exchange for election tickets to the upcoming assembly polls in Punjab.

Kejriwal was on way to Ludhiana to start a four-day tour of Punjab.

Sisodia said though the police had been informed of a possible law and order situation, not much was done to prevent the mobbing.

"Since yesterday police had been requested to remain present because there was a possibility of something untoward happening, please be alert. But the police was not even alert," Sisodia said.
